Overview
R5F104GCAFB#10 from Renesas is a 48-pin LFQFP, 128 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), targeting industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F104GCAFB#10 datasheet, R5F104GCAFB#10 pinout, R5F104GCAFB#10 application, or R5F104GCAFB#10 equivalent, key selection criteria include its 128 KB code flash + 4 KB data flash, 10-bit 20-channel ADC with internal temperature sensor, dual UART/LIN support, and industrial-grade −40°C to +105°C operation under G-grade qualification.
Technical Context
The R5F104GCAFB#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions within a 1 MB address space. It integrates a Data Transfer Controller (DTC) for autonomous memory transfers triggered by 19–26 event sources via the Event Link Controller (ELC).
Its analog subsystem comprises an 8/10-bit ADC (20 channels, internal 1.45 V reference, temperature sensor), an 8-bit DAC (2 channels, 0–VDD output), and up to two comparators with window/high-speed/low-speed modes. Serial interfaces include 3–4 UART/LIN channels, 4–10 I²C channels, and 3–8 CSI (SPI-compatible) channels.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GCAFB#10?
The R5F104GCAFB#10 operates at up to 32 MHz with a verified performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator, and is specified under standard industrial conditions (VDD = 1.8–5.5 V, TA = −40°C to +105°C). The R5F104GCAFB#10 maintains this throughput while supporting ultra-low-power modes that scale current linearly with clock frequency.
Does the R5F104GCAFB#10 support LIN bus communication, and which UART channels are qualified?
Yes, the R5F104GCAFB#10 supports LIN 2.2-compliant communication via its UART channels, specifically UART0, UART1, UART2, and UART3 - all capable of generating accurate LIN break fields and handling sync/identifier/data fields in hardware. The R5F104GCAFB#10's UART modules include dedicated LIN timing control registers and automatic checksum calculation, eliminating software overhead for protocol compliance.
What are the flash memory organization and security features of the R5F104GCAFB#10?
The R5F104GCAFB#10 contains 128 KB of code flash organized in 1 KB blocks, with programmable block erase/write protection to prevent unauthorized access. It supports on-chip debug, boot swapping for safe firmware updates, and a flash shield window that restricts write access to designated memory regions during runtime. These features are implemented in hardware and require no external components - critical for secure industrial firmware deployment in the R5F104GCAFB#10.
How many analog input channels does the R5F104GCAFB#10 support, and what reference options are available?
The R5F104GCAFB#10 supports up to 20 analog input channels with 10-bit resolution. Reference voltage options include external AVREFP/AVREFM pins or the internal 1.45 V reference, selectable per channel via register configuration. The integrated temperature sensor is factory-calibrated and shares the same ADC resource, enabling simultaneous thermal monitoring without additional components in the R5F104GCAFB#10 design.
Is the R5F104GCAFB#10 pin-compatible with other RL78/G14 variants in the 48-pin LFQFP package?
Yes, the R5F104GCAFB#10 is fully pin-compatible with all RL78/G14 devices in the 48-pin LFQFP (FB) package, including R5F104GEAFB#10, R5F104GHAFB#10, and R5F104GGAFB#10. Pin functions, power domains, reset behavior, and peripheral mappings are identical across these variants - enabling direct substitution in existing PCB layouts when flash/RAM requirements change, provided the G-grade temperature specification remains appropriate for the R5F104GCAFB#10 application.
